Hello,
I am having problems, getting my asterisk-domU to work properly. It consists
of the following components:
- Debian Etch under Xen-3.1 with a 2.6.18-kernel
- Asterisk 1.2.24
- mISDN-1.1.5
I have 2 HFC-ISDN-cards, which I pass through to the Asterisk-DomU in
permissive mode. This is working fine.
The strange problem is, that the two HFC-ISDN-cards are not beeing initialized
by the mISDN-driver if there are more than 3 other domUs up and running.
I get the following error message:
HFC-PCI: Error allocating memory for FIFO!
FATAL: Error inserting hfcpci (/lib/modules/2.6.18-xenU/extra/hfcpci.ko): No
such device
If you look into the mISDN source-code you will find the following snippet of
code in /drivers/isdn/hardware/mISDN/hfc_pci.c, which produces the above
error:
/* Allocate memory for FIFOS */
/* the memory needs to be on a 32k boundary within the first 4G */
pci_set_dma_mask(dev_hfcpci, 0xFFFF8000);
buffer = pci_alloc_consistent(dev_hfcpci, 0x8000, &hc->hw.dmahandle);
/* We silently assume the address is okay if nonzero */
if(!buffer) {
printk(KERN_WARNING "HFC-PCI: Error allocating memory for
FIFO!\n");
return 1;
}
But what is even more strange is the following:
As far as I can see, mISDN will also not initialize the HFC-cards in the
asterisk domU if I have not started all the other domUs at least once. Than I
have to shut down one of the other domUs, initialize the mISDN drivers, and
restart the other domU again.
Just in case it might help to solve the problem, I will post the output of
lspci -vv in the case where mISDN CAN initialize the cards and in the case
where it CANNOT. Here it comes:
mISDN CAN initialize the cards:
asterisk:~# lspci -vv

Has anyone ever encountered such a strange problem? Does anyone know how to
solve this problem?
Thanks!
